Windshield Base Display Segmentation for Vehicle Information Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motor vehicles, the current multiple display units at various locations often lead to information being inaccessible or too small for rear occupants, making it difficult for them to read relevant information.
Innovation Solution
A method where information is reproduced on a large base display at the bottom of the windshield, divided into sub-areas for different classes of information, allowing clear and unambiguous display of driver-relevant, passenger-relevant, and general interest information, ensuring visibility for all occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display units are arranged at various locations in the vehicle interior, then comprehensive information can be provided to occupants, but rear occupants cannot see relevant information clearly or read it due to size and position limitations
Solution Approach 1:
The display area is segmented into multiple sub-areas, with each sub-area assigned to a specific class of information (e.g., driver-relevant information, passenger-relevant information, general information). This segmentation allows different types of information to be organized in distinct regions, making it easier for occupants to locate and read relevant information without confusion.
Solution Approach 2:
The display is positioned at the base of the windshield, utilizing the vertical space and the large horizontal area at the front of the vehicle. This dimensional placement transforms the display from a traditional dashboard location to a prominent position that is visible to all occupants, including rear passengers, thereby solving the visibility and accessibility problem.
2Loss of information
If information is displayed on traditional dashboard displays, then driver-relevant information can be shown, but the information is too small or positioned such that rear occupants cannot read it
Solution Approach 1:
Multiple display functions are merged into a single large display unit located at the base of the windshield. Instead of having separate displays for different occupants, the invention combines all information display functions into one unified display that serves the entire vehicle interior, ensuring that all occupants have access to visible and readable information.
Solution Approach 2:
The display leverages the large horizontal area at the base of the windshield, utilizing the extensive space available in this region. This dimensional advantage allows the display to be sufficiently large for all occupants to read information clearly, while still maintaining organized sub-areas for different information types.
3Ease of operation
If a large display is placed at the base of the windshield, then all occupants can see information clearly, but the display may cause driver distraction
Solution Approach 1:
The display is divided into distinct sub-areas, with driver-relevant information placed in specific regions that are easily visible to the driver without requiring excessive attention. This segmentation allows the driver to quickly locate important information while less critical information is organized in other areas, reducing overall distraction.
Solution Approach 2:
Different regions of the display have different functional qualities - driver-relevant information sub-areas are positioned and designed for quick driver access, while other sub-areas serve passenger or general information purposes. This local differentiation ensures that the driver is exposed only to necessary information in a controlled manner, minimizing distraction while maintaining readability.
